Re: Penryn TDP @ 0.3 Watt for Deep Power Down

Good catch, Jokerman. I found it interesting that a number of thermal specs have improved with Penryn vs Merom.

 TDP @ 1.2GHz Low Freq Mode (LFM) - 25W -> 22W 
 TDP @ Stop Grant and LFM Voltage - 6.9W -> 5.0W 
 TDP @ Sleep State and LFM Voltage - 6.7W -> 4.8W 
 TDP @ Deep Sleep and LFM Voltage - 4.3W -> 2.2W 
 TDP @ Deeper Sleep and LFM Voltage - 2.0W -> 1.7W 
 

Penryn seems to be lower power in a number of important sleep states. It should lead to some spectacular idle and average power numbers, especially with the Deep Power Down mode @ 0.3W TDP.

Note, too, that junction temperature was increased, which allows systems builders to design less expensive cooling solutions:

 
 Tj - 100C degrees -> 105C degrees 
 

IMO, This should not be overlooked as another important step towards creating smaller form factor devices.
